Amid the massive influx of Star Wars gadgetry, one toy has stood out more than any other: Sphero’s awesome remote- controlled BB-8 droid.

Ever since she first rolled onto the stage at the Star Wars Celebration event in Anaheim, BB-8 has captured the imagination of those both struck by her lovable disposition and in awe at the practical effects, as up until then pretty much everyone had assumed it to be a result of CGI effects. Nope, it’s the real deal and now you can buy your very own.

Controllable via your smartphone (once you have downloaded the free app), what looks like R2-D2’s cute cousin is sure to be the must-have accessory this Christmas. Zoom in on our teardown to find out how this little ball of fun is able to move around and always manage to keep its head in the same place, even when its rolling.
